| Abstract |
- Knowledge of the ecology, spatial distribution and conservation status of fish populations is achieved by fishery-dependent techniques, and by more recently developed non-invasive fishery-independent techniques. Passive acoustic monitoring (PAM) is a fishery-independent method that provides remote sensing of soniferous species, populations, communities and ecosystems by recording soundscapes and their components.
- A case study is presented to demonstrate how PAM can contribute to a dynamic understanding of fish distribution, ecological preferences and conservation status. This case study refers to the cusk-eel Ophidion rochei (Ophidiiformes), a nocturnal, behaviourally cryptic, soniferous fish species, described as uncommon and rare in the scientific literature, and listed as Data Deficient in the IUCN Red List.
- A systematized literature review was carried out using Ophidion+rochei as the search term, and by grouping records into two main categories: (i) traditional techniques (including all fishery-dependent techniques and underwater visual census); and (ii) PAM.
- This review highlights how PAM has provided new sightings of O. rochei at a rate three times higher than all other monitoring techniques combined. In contrast with the knowledge achieved to date by fishery-dependent techniques, the reported acoustic mass phenomena indicate that this species can be very abundant. Ophidion rochei was found to inhabit a wide range of depths and ecosystems, at least throughout the Mediterranean basin.
- This paper supports the urgency and the importance of relying on the integration of different fishery-independent techniques for multidisciplinary monitoring, in line with the Goal 14 requirements of the UN Decade of Ocean Science for Sustainable Development.
